摘要: Abstract This paper discusses ZrO2:Ho3+ and ZrO2:Ho3+/Yb3+ coating formation by the plasma electrolytic oxidation (PEO) of zirconium in alkaline electrolyte containing Ho2O3 Ho2O3/Yb2O3 particles, respectively. The morphology, chemical phase composition, as well down- up-conversion photoluminescence (PL) coatings, were investigated. Down-conversion PL emission spectra excited 280 nm radiation are composed broad band associated with ZrO2 host bands corresponding to f–f transitions Ho3+. main Ho3+ at around 540 nm 550 nm assigned 5F4→5I8 5S2→5I8 transitions, down-conversion intensity 450 nm (transition 5I8→5G6) strongly depends on concentration incorporated into coatings. That is, it duration PEO process particles electrolyte. increases rising reaching a maximum Ho:Zr ratio about 18⋅10−3 shows quenching for higher values. Excitation coatings 980 nm laser diode results appearance strong green (5F4,5S2→5I8), weaker red (5F5→5I8), NIR (5F4,5S2→5I7) emissions. An increase increasing Yb3+ indicates an efficient transfer energy from ions ions.
